Specification of Letters Patent.

Patented Nov. 30, 1909.

Application filed January 10, 1908. Serial N 0. 410,076.

To all whom it may concern:

Be 1t known that I, DAVID J. IIAVENSTRITE, a citizen of the United States, residing at Newark, in the county of Essex and State of tion thereof whereby a number of separate the upper surfaces of the headers. The

ice cakes may be formed in a freezingtank, which ice cakes can be individually removed.

In the embodiment of my invention hereinafter set forth, I disclose a tank for containing the water to be frozen, in which tank are disposed a plurality of separate parallel tubes, preferably fixed in said tank and extending upwardly from the floor thereof: the upper ends of said tubes are closed, and their inner-construction is such as to permit the circulation of fluid within them. Said fluid may be either refrigerating fluid or thawing oif fluid. The said tubes are also preferably arranged in groups, each group leading from a separate header, so that upon each header and upon its associated tubes and between said tubes and around the periphery thereof, is formed a.

off from tubes and header and may then be removed vertically out of the tank without disturbing said tubes and header.

The invention consists in the various combinations embodied in my said apparatus as more particularly set forth in the claims.

In the accompanying drawings-l igure 1 is a vertical section of my ice making ap paratus and of a. portion-of the tank containing the same on the line 1. 1. of Fig. 3. Fig. 2 is a section on the line 2. 2. of Fig. 3, and Fig. 3 is a section on theline'3. 3. of

Similar characters of reference indicate like. parts. p

4 is the tank containing the water to be frozen and having a substantially level floor. Said floor is made up of headers 5 having horizontal upper surfaces and placed end to end, and of spacing blocks 6 of wood disposed between said'headers and having their upper horlzontal surfaces registering with construction of said headers is the same for all, and any desired number of them may be used. Each header consists of an outer shell 7, preferably of cast metal intern-ally divided intothree chambers 8, 9, 10, by the partitions 11, 12, which may be integral with the outer shell. Extending upwardly from the header are tubes which communicate directly with the chambers 8, 9, and are closed at their upper ends. \Vithin said tubes and communicating with the chambers 9, 10, are smaller tubes open at both ends. These tubesaredisposed in various ways: thus as shown in Fig. 1 and in connection with the header A, Fig. 3, the eight tubes 13, ll, 15, 16, 17, 18, 19,20, are disposed in two rows. The tubes l3, 14, 15, 16 communicate with the chamber 8 and their inner tubes 21, 22, 23, 24: communicate with chamber 9. he tubes 17, 18, 19, 20, communicate with chamber 9 and their inner tubes 25, 26, 27, 28 communicate with chamber 10. As shown in Fig. 2, and in connection with the header B, the seven tubes are disposed in two rows but staggered, in which case the five tubes :29, 30, 31, 32, 33 communicate with chamber 8 and their inner tubes with chamber 9. The

remaining two tubes SH, 35 communicate with chamber 9 and their inner tubes with chamber 10.

The headers which are disposed end to end 'asA, A, B, B, Figs. 1 and 3, are connected by short pipe sections or thimbles 36 extending from the chamber 10 of the next header. The end headers of each series A,

A, B, B, are provided with inlet pipes 37,,

which extend through the wooden blocks 6 and the tank wall adjacent thereto.

The operation is as follows: Any suitable fluid refrigerating medium enters the headers by the pipes 37 and proceeds through the outer tubes connected with chamber 8 to the inner tubes and so to chamber 9; thence to the outer tubes communicating with chamber 9 to their inner tubes communicating with chamber 10, and so to the next header by pipe 36, or from the last header of the series back to the source of supply. The circulation of the refrigerating medium through all of the headers and tubes causes an ice cake to form between and around the peripheries of each group of tubes associated with any given header. Thus in Fig. i, the cake C is formed on the group of tubes hich are on header A, and in Fig. 2 will beseen two ice cakes C, E, each formed respec- 2. In an apparatus for making plate ice, a 0 tank having a substantially level floor, a header having its u er surface horizontal forming part of sai cor, parallel tubes lo cated at a distance from the vertical walls of said tank closed at their upper ends hav- 45 h in substantially smooth external periphubesqbut each cake s to cries extending vertically upward from said ran and free from said adheader, and partitions in said tubes and 210, acent ealtesalthougli in contact with the header: whereby-liquid circulation may be *li'eader'at'i l 'e'r'surfac'e.

In an apparatus for making late ice, a
